Application March 27, 191i. No. 81?,626.

To all whom it mayconccm Be it known that I, Join: Cnnvennao, a resident of the city county, and State of New York, have invented certain new and useful improvements in El ,ctric Regulation as set forth in the annexed specification and drawing forming a part t erect.

My invention pertains t that class or electric regulation wherein automatic regulator is employed and has for its object to provide means for properly connecting the regulator in operative relation. to a sys-- tem, and also means for cutting out the regulator when it is de ed to cut out the same.

Figure l a agrammatic rep c tion, of one type or system embody invention. Figs 2 is a modified forrr tem embodying my invention.

loyed in the system or 1F 1 and In Fig, l, 1 re resents adynamo or erator which may be provided with the usual field coil 2 and any suitable regulator 3, in this case merely indicated as a carbon pile. 4 represents the positive lead of the generator which may be connected with the storage battery 5 and to one side of the lamp and translation circuit switch 6 the opposite side of which is connected with the translating circuit main 7 communicating with the lamps or other translating devices 8 which are also connected to the main 9 which is carried to one side of the ire ulating element 10, the opposite side of whi h. in connection with. the negative generator lead 11,, in connection with the store tery 5.. The regulating element 10 o1 any desired charactercapable of reg lating the translation circuit, and in this instance is indicated as a carbon pile operated by the lever 12 normally drawn in a down ward direction by adjustable spring 13 in such manner as to compact the carbons and lower the resistance thereof.

The lever 12 is provided at one extr ,inity with the core 14: surrounded by the solenoid 15 in such mannor that excitation of the solenoid tends to raise the core and increase the resistance 10 One end of the solenoid 1-3 is connected with the wire 16 in communication with the clips or contaci lingers 17 adapted to engage terminal or the removable 18 the other terminal of which may be pressed between the fingers 19 which are connected as by wire 20 with the main 3'. The removable 'nore clearly shown in F 3. The opposite nd of the solenoid 15 is connected with one of the small carbon. pile 521 the other end which is connected as by wire with the ad 11. 23 is a lever normally drawn in a .ownward direction. against the adjustable crew 2 hy means of adjustable spring 25 5 provided at one extremity with the corv surrounded by the solenoid 2'? having end connected with the wire 16 ashy 8 and the opposite end connected with as by wire 9 The entire regulad upon a base indialso mount the adapted to an may he readily reand and var rhi ch he s cate like parts o the current in the coil 15 to cause the resistance 16 to hold the e upon the translation circuit constant. A further modification is shown in this sysin that an adjustable resistance 39': is placed between Contact fingers 82 and the lead 9., where manual regulation of the translation circi. may be accomplished when the automatic regulator is cut out.

The practical operation of my invention, referring particularly to Fig. 1, is substantially as follows:lf the generator be running: and supplying current to the battery 5 and the switch 3 be open, 110 current will be consumed in the translation circuit or by the regulator itself. if the switch (3 be closed, current will flow from the generator through lead 41 switch 6, main 7 translatdevices 8 main 9 caroon pile 10, and lead ll the generator and the translation circuit and may be governed by proper manipulation of the resistance 10. Current will also flow from the main T through the wire 20, iin ers 19 fuse 18, fingers 17, wire use and its engaging contact fingers are 16, solenoid 15, carbon pile 21, and Wire 22 were lead 11 and by excitation of the coil 15 tend to raise the lever 12 and increase the resistance 10. Current Will also flow from Wire 16 through wire 28, solenoid 27, 'Wire 29 to the main 9, and, l so adjust the springs 25 and 13 that the solenoid 27 Will so regulate the carbon pile 21 and so govern the current in the coil 15, and the resistance of the pile 10, as to hold constant Voltage across the mains 7 and 9 or upon the translating devices. it now for any reason it be desired to cut out the translation circuit regulator, as for example should. the same operate im 15 properly, I Withdraw the fuse member 18 from the fingers 17 and 19 and insert the same between the fingers 31. and 82, the said fuse being heavy enough to carry the desired translation current. This short-circuits the 2 carbon pile 10 and thus obviates any trouble that the same might be causing through im-.

proper action. The removal of the fuse 18 from the lingers 17 and 19 interrupts the current flowing from the Wire 20 through the coils 15 and 27 and thus Waste of current through the regulator mechanism is avoided and any improper working brought about through the action of the said coils is I also suppressed. it Will thus be obvious that 30 the simple transferring of the member 18 renders the operating; mechanism of the regulator inert and diverts the current around the regulating element 10 and pro te cts the same from any injury that might \occur due to improper performance of the regulator.

The operation of the system shown in Fig. 2 may readily be followed out from the Ad above description of the operation of Fig, 1, it only being: necessary to remember that 1ncrease in voltage across solenoid 27 tends to Weaken the coil 15 and thus allow spring 33 to increase the resistance 10 and that decrease in voltage across coil 2'? allows the inn" 535 to decrease the resistance 21, in-

se tilGClllllQ-Dt in the coil. 15, and thus e ease the resistance 10, and that When fuse member 18 is removed. from its W contact lingers 1.? and '19 and inserted beto .en the lingers 31 and 32, the voltage upon the translation circuit may be regulated by hand by manipulation of the adiusta bio resistance 84. it will be noted that invention is particularly applicable to systems of the character shown in Fig. 2, wherein cutting: out of the automatic reguns," mechanism coils causes an increase in the governing or controlling resistance 10 to the maximum. This invention is especially useful in electric lighting: systems employed upon railway cars Where, it trouble develops in the regulator for the translation circuit, there is usually no one present to n'ialre the proper adjustments or look after the trouble and it moon it is desired to have some means whereby an unskilled hand, as for example a porter, may easily cut out the entire regulating mechanism which is improperly performing, as for example should the regulator be hunting and causing a bad fluctuation in. the lamps. This arrangement provides asimple means whereby such a hand could simply cut out the entire regulating mechanism until proper adjustments or repairs can be made.

I do not wish in any Way to limit myself to the exact construction set forth in the drawing nor the exact mode of operation described in the specification of this application, for it will be obvious that vz'iriations may be made therein Without departing from the spirit and scope of my invention which is as set torthin the following claims.
